Do gamma oscillations play a role in cerebral cortex?

Do gamma oscillations play a role in cerebral cortex?

Highlights • Cortical gamma rhythms have low and inconsistent power. • Cortical gamma rhythms are affected by low-level stimulus features. • Coordinating gamma phase across multiple areas is difficult given conduction delays. • Spike-related activity can bias phase estimation between gamma and spiki...
